HOLDING DEVICE FOR BRUSH-BLANKS SPECIFICATION forming part of LettersPatent No. 660,589, dated October 30, 1900.

Application filed May 25, 1899.

T0 aLZZ whom. it may concern.-

Be it known that I, WALTER C. READ, a citizen of the United States,residing at New ark, in the State of New Jersey, have inventedImprovements in Holding Devices for Brush- Blanks, of which thefollowing is a specification.

My invention relates to holding devices for brushes and the like, and isintended to cooperate with a trimmer or cutter which is adapted normallyto trim or out brushes to a flat surface, the special purposes of theimprovement being to provide means wher'eby the cutting or trimmingmachine may be used for trimming brushes to a curved face.

In the accompanying drawings, Figure 1 represents the invention inperspective as applied to a cutting machine having straightedged cutterswhich are adapted to cut flat faces on the blank. Fig. 2 is an enlargedview of the improvement detached from the machine, and Fig. 3 is a viewsimilar to Fig. 2 of a modification.

The cutting-machine may be of any ordinary type comprising a standard Aand rotary cutters B, which are adapted to cut or trim flat faces on thebrush. At one end of the table standards a extend vertically, and thesecarry a bracket 1 made up of arms 2 and a cross-bar h, the said armsbeing held by collars 3 adj ustably secured to the standard a bythumb-screws 4:- The cross-bar 19 carries a hanger j, through which arod 0 extends, being supported adj ustably by a collar 5, resting uponthe hanger-j and secured to the god by a thumb-screw 6. The rod 0carries at its lower end a bearing, through which a barf extends, andthis bar has sleeves g at its ends, through which extend vertically therods E, to the lower ends of which a brushholder d is secured. Thevertical position of the rods E is determined and fixed by nuts 72.engaging screw-threads on the rods above and below the sleeves g. Thebrush-holder may be of any ordinary form, having suitable clamping meansto hold the brush directly over the cutters, as shown in Fig. 1. The barf has rocking movement in the bearing c, so that by moving thebrush-holder laterally it Serial No, 718,273. (No model.)

will swing in the arc of a circle,- of which the axis of the rodfis-thecenter, and thusalaterally-curved face may be given to the brushblank.The hanger j is loosely journaled upon the cross-bar b of the bracket 1,and as this cross-bar extends in a plane at right angles to the plane ofthe rocking bar f the brush-holder may be given a swinging move mentfrom front to rear, so as to describe an arc the center of which will bethe axis of the hanger j. From this construction it will be seen that acurved face may be formed on the brush both laterally andlongitudinally.

In Fig. 3 is shown a modification which relates more particularly to theform of the sup-- porting-bracket, this consisting in this instance ofconverging arms 2, having a hanger j" at the meeting-point of the arms,from which the support for the holder is hung. In this form the barf notonly has rocking movement to present the brush-blank laterally to thecutters in the arc of a circle, but the bar f may slide longitudinallyin the bearing 2', so that all parts of the brush-blank may be broughtover the knife by sliding the barf in the bearing In this form the brushwill be cut on a curve in one direction only, and the rounded surface ofthe blank will form a portion of a cylinder.

I claim as my invention 1. In combination, the standards, the bracketvertically adjustable thereon, and the holder suspended from saidbracket and capable of having a longitudinal reciprocating movement anda transverse swinging movement, substantially as described.

2. In combination, the standards, the bracket, the bearing suspendedfrom said bracket and the holder having a rod slidably and rotatablymounted in said bearing whereby said holder may be reciprocatedlongitudinally and swing transversely in the arc of a circle,substantially as described.

3. In combination, the holder, the bearing 7;, the rod f turningtherein, means connecting the rod with the holder, the rod b extendingin a plane at right angles to the rod f, the hangerj turning about therod b, the vertically-extending rod 0 held by the hanger 7" arms 2 andthe standards a to which the arms are secured, substantially asdescribed. 16

In Witness whereof I'h'ave hereunto set my hand in presence of twowitnesses.
